LED Canopy Light is a common kind of light. You can see this kind of light on the road. Do you know the life of LED ceiling light and what is it?
About 70% of LED ceiling light failures are caused by packaging, so packaging technology is a key technology for LED ceiling lights. The cause of failure caused by led package is very complicated. The main source has three parts:
First, the packaging material is not good, such as epoxy, silica gel, phosphor, susceptor, conductive adhesive, solid crystal material.
Second, the package structure design is unreasonable, such as material mismatch, stress, crack, open circuit, and the like.
Third, the packaging process is not suitable, such as loading, pressure welding, dispensing process, curing temperature and time.
In order to improve the reliability of the device package, firstly, the quality of the material should be strictly controlled in terms of raw material selection. In addition to considering the light efficiency and heat dissipation in the package structure, it is also necessary to consider the heat rise matching problem when a plurality of materials are combined.
In the packaging process, it is necessary to strictly control the process flow of each process, try to use automation equipment, ensure the consistency and repeatability of the process, and ensure the performance and reliability indicators of the LED Canopy Light Fixtures.
